Hydrophilic objects
Web1 dec. 2024 · It is generally believed that a water-repellent surface is necessary for an object to be afloat on the water surface. However, some studies declare that hydrophilic objects can float on water by surface tension, while apparent CA (θ*) of the object no longer obeys the Young’s equation (Fig. S5) [33]. WebMaterials and molecules that have an affinity for water are hydrophilic; a hydrophilic surface will cause water to spread, and molecules that are hydrophilic tend to dissolve …
